An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar \n composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, Oto2 percent slopes, ima phase of the Alpha series.
Some map units are made upof two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha-Beta complex, OtoO percent slopes, ioanexample.
An association io made upof two or more geographically associated soils or
miscellaneous areas that are shown em one unit on the maps. Because ofpresent
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, Oto2 percent slopes, ieanexample.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped eo one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
upof all of them. Alpha and Beta soils, Oto2 percent slopes, iaonexample.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little orno vegetation. Rock outcrop ioanexample.
